IMPROVEMENT IN VAPORIZERS FOR STEAM-HEATING APPARATUS.

, Specification forming part of Letters Patent No. 131,807, dated October 1, 1872.

` To all whom it may concern:

Be it known that I, GEORGE S. BASSETT, of Holyoke, in the county of Hampden, and State of Massachusetts, have invented a certain Improved Vaporizer, of which the following is a specilication: i

My invention is designed for use in those rooms of cotton manufactories and other like places, in which it is desirable to increase the natural moisture of the atmosphere by introducing live steam, and is to be connected with the steam-heating pipes, or other steam supply, by suitable connections, a stop-cock being inserted in such connection to control the supply of steam.

Said'invention consists in constructing a steam-diusing chamber, having an opening for admitting the steam, and perforations for 4 allowing it to escape in fine jets into the room,

i a section made by a vertical plane passing through the axis of the'chamber, shown in` Fig. 1, and from sideto Vside of the same, 4as shown; Fig. 3 isa horizontal section through the line a' .r in Fig. l; and Fig. 4 is a horizontal section through the line y g/ in Fig. l.

A is a shell or chamber, preferably of cast metal, having one end slightly enlarged and perforated at a. a for the escape of the steam in jets. The other end is provided with a flange for bolting the vaporizer tothe floor. A steam supply-pipe, provided with a stopcock, is connected with the chamber A at E. e

An opening at D allows the condensed Water to pass into a drip-pipe properly arranged beneath the floor.` The diaphragms BV and G can be cast in one piece with the chamber A,

by a suitable construction of patterns, and are preferably :made in that way, although the chamber may be made in sections, and the diaphragms fastened in position before the sections are joined together. The-lower diaphragm C is located so that any water entering with the steam will impinge against it, and descend by gravity and probably pass out of the current of steam and into the drip. If, however, any water should` pass beyond the angle cof the diaphragm C, either moving onward with the steam, as shown by the curved arrows, or being forced along from the condensed water having accumulated so as to rise above the lower edge of C, the position of the diaphragm B is such that the water will almost certainly pass into the angle formed between the inside of the diaphragm B and the side of the chamber, and will thence descend by gravity and pass out at the drip. The water being thus checked and detained by the diaphragms, the steam passes out of the perfbrations carrying little or no condensed water with it. The particular conformation of the diaphragms is not so essential .as the relative position of the same, which should be such that the lower edge B shall overlap the upper angle of C, in a manner substantially as shown.

A modification of the before-described device, for use in rooms where the same cannot be conveniently located on the iloor, consists in removing the iiange at the bottom of A, and supporting the chamber at D uponthe end of a steam-supply pipe set vertically or nearly so, and dispensing with the supply- `pipe at E. The drip will then pass out of the chamber into ,the steam-supply pipe in the same manner as in some forms of radiators, andV the lower edge of the diaphragm C will be iiared so as to approach more nearly to the right-hand side of A, as shown in Fig. 2.

I make no claim to a steam-diffusing chamber having perforations formed therein, but

without diaphragms for checking the movepose specified. f
